Lyman Spitzer Jr.Died 31 Mar 1997 at age 82 (born 26 Jun 1914). American astrophysicist who advanced knowledge of physical processes in interstellar space and pioneered efforts to harness nuclear fusion as a clean energy source. He made major contributions in stellar dynamics and plasma physics. He founded study of the interstellar medium (gas and dust between stars from which new stars are formed). Spitzer studied in detail interstellar dust grains and magnetic fields as well as the motions of star clusters and their evolution. He studied regions of star formation and was among the first to suggest that bright stars in spiral galaxies formed recently. Spitzer was the first person to propose the idea of placing a large telescope in space and was the driving force behind the development of the Hubble Space Telescope. |
